As may be i'eediiy observed fem *die len*- giudinei eeeifm of Fig. 2 from the transverse section ei? Fig. 3, 'he sweiii; in the ferm ei iioiew'ifeund simi ei pi'oieeiiel: ai: one. sifie of the ring 7. i'ze paiicuier ieeienee to Fig. 3, it Wi be seen that ei' miie? "J snugiy embraces the hexerei ei'ieut whe eniie eeuinfeenee ef the ieitei. The coiiar 7 heeereeeimet be eceidemeiiy moved 'ransvezsey e the barrel whereby 'ehe pin .is pressed inwer t0 compress the ufhe l'l and expei the iikfom ehe ink to depress the pin. No possible pressure of' the hond in 'writing can so move the ring 7 as to expel tbe init. Since the member 8 is in the ioiin ot e, hollow projection und the ringr 7 embraces the ent-ifo circumference of tile borrel 6 the pin oestiid 9 is entirely inclosed9 indy be readily seen from a, com porison ot litige, 52 and 3, the pin is protected troni breaking end is supported in its true position end no sediment is permitted to accumulate about the pin or in the borrel "to impair tlie tree operation ot the device. 'lllie niei'nbei 8, being u projection or :in ebiuptly extending portion :torina with the body of tite ring 'i' en :ibinpt shoulder adepted to i'eleese the pin 9 somewhat suddenly ivlien "oi-ought into register Witll'tlie projec tion El and permit tlie repid expansion of the tube ll end the consequent tepid filling oi the sziine-ii much desired result' in self- -tillingn fountain pens. 'lliese shoulders ere :termed one mit each side of the projection ond serve :is stops indicating the turning of tlie ring l tliroiigli eucii complete revolution ond .limiting the further turning of the ring. This proj .ion 8 is the only projecting portion carried upon the borrel of tlie pen, and initcnole7 :is liest seen in .FigA l, upwardly or outwardly from tbe plane of tlie back or topy oil the gon point it The projection 8, tlie'ii'e'lore, between tlie torctinger end the thumb when the pen is lield in position .tor g end iis-siste the user in holding the pei in proper position 'in the hond, and. Serves as on indicator toi' quickly clelxerniin-A by grasping the borrel in the hund., tlie t position of tbc gpen for Writing. lio correct positioning of the stud normali enten/ded position may be leterniined by tbe adjustment ci' the z to the bock ogt the pen point fountain pen be placed upon si with e slight inclination Where l tei'idencjv for the barrel to roll, the o f rilies the sin1 ce and holds lifoni tolling; to any appreciable l. lieve shown und desi ined one ol my invention, it obvious 'ictefi tlie'eto but ie inocente l enough to cover all structuies tl'iet corne within the scope of the annexed cleitne.

lt is to be noted that the ring? engegges the periphery of the pen borrel onveli points within its lateral limits, and that the swelling or com projection 8 entends :ifi-om its close fitting; annular rim from e, point Witliin its sides or lateral limits. This serves to retard the rotary movement of the ring so us to preventinadvertent tin'ningm of the lutter which inadvertent turning would cause the ejection ot the ink from the tienible tube. The swelling; or projection 8 forms an abrupt stop and thus the inedvei'tent turning is meesurebly prevented end the position of the stop in relation to the borrel of the pen readily determined so as to enable t-lie user of the pen to know when tlie pen is in Seite condition..

Having thus described my invention, what ll claim is;

l. in u self-61nd, fountain pen ei borrel having en opening girougli one side thereof, :i collapsible tube in tlie borrel, e, tube coinpressing pin in the bei-rel und extending outwardly through seid opening, und e closely itting ring rotatably mounted on the barrel over the opening end bearing et its inner wall against the pin, seid ring bev ing a radial projection et one side end be tween the edges of the ring with on cocon tric inner Wall whereby to edrnit oi the 'elitension of. the pin to its outermost position, the sides ot seid projection merging into the edges ot the rin whereby to completely inclose the pin an prevent dirt entering seid opening in the borrel.

ln a self-filling fountain pen7 e, borrel. having an exterior annular groove end en opening through one side intersecting tlie groove, :i collapsible tube in the borrel, tube compressingl ineens in the barrel including :i pin projecting; outvvnidly through said opening und :i rotatable ring seated in the groove closely itting tlie barrel end beni'n ing against the outer end of seid pin, said ring having e hollow projection et one side the inner Woll. oil which is eccentric to the inner well "tbe ring and adopted to rc ceive the pin' when the letter is in its outer most position, the sides ot seid projection bearing against the borrel whereby to tonrn pletely inclose the pin when extended to' prevent dirt entering said openingu 'iinjned et the city out New orli7 county olf New York end Stute oltlew lllotlt, this 22nd doy of Morcin 3291i.
